ST485ECDR ST RS-485/RS-422 Transceiver | 8-SOIC | 5V, 500kbps, Half-Duplex

Product Overview

The ST485ECDR is a low-power, half-duplex RS-485/RS-422 transceiver from STMicroelectronics, designed for balanced data transmission in industrial and communication systems. It operates from a single 5V supply and features a driver output capable of delivering up to ±60mA, with a receiver input impedance of 1/8 unit load (allowing up to 256 nodes on the bus). The device supports data rates up to 500kbps and is available in the compact 8-SOIC package, making it ideal for space-constrained applications.
